libspectre 0.2.8 (01 July 2016)
===============================
This is another bugfix only release in the libspectre's 0.2 series.
Marek fixed the document rotation with newer versions of Ghostscript (Bug #76450)
Build was also broken with Ghostscript >= 9.18 and has been fixed.
Fixed a compile warning due to a comparison of integers of different
signs reported by Daniel Macks when building on OS X (Bug #56476)
Makefiles were updated to properly use CPPFLAGS instead of CFLAGS as
suggested by Daniel Macks (Bug #56481)
